John Chrysostom likely preached the following circa 390 AD during his priesthood in Antioch in Syria. It is taken from §1 of his ninth homily on Colossians, an exposition of 3:16,17.

Listen, I urge you, all you who care about this life, and procure books that are medicines for the soul. If you do not desire anything else, get at least the New Testament, the Acts of the Apostles, the Gospels, as perpetual teachers. Whenever grief befalls you, delve into them as if they were a medicine chest. Find relief from your suffering there whenever you experience detriment, death, loss of family members. Yes, do not so much delve into them as absorb them entirely; have them in your mind. This is the cause of all the evils—not knowing the Scriptures.
